Before Watching
-
"Einstein said time is that which is indicated by a clock. I
think I know what a clock is, therefore I think I know what time
is." (Joe Hafele);
-
"Time is the thing out there that flows and I go with the flow."
(Kip Thorne);
-
"Time is nature's way to keep everything from happening at
once." (John Wheeler)
After Watching
-
Have students debate this quote from physicist Stephen Hawking:
"Time travel might be possible, but if that's the case why
haven't we been overrun by tourists from the future?"
-
Discuss with students how popular media portrays time travel in
science fiction literature and movies, such as "Back to the
Future," "Terminator I" and "II," "Contact," and "Star Trek."
Why do students think time travel is such an appealing subject?
